Just looking for some general advice, wondering if this list is maybe too fine tuned?

From looking at it I wouldn't say it is overtuned, but I would say it could end up feeling very one dimensional. HH melta squads, recon squads and tyrants can all end up feeling very point and click after a while from experience.
For the list itself I'd say you're likely going to struggle on objectives. Unless I'm missing something, while you have 4 line units on paper, the command squad and lernaean's lack any real mobility; and you want the recons watching the home objectives out of the way rather than infilitrating into mid-field.
Also what's the rationale for the all the nuncio-vox's? Night Lords? Otherwise that's 30 points on wargear that helps you to solely reroll the scatter if you deepstrike the bikes.
